No, it’s not fixed – that example page shows that if people comment on blog articles on Facebook, the comments show up on the blog, but there’s no standard, stand alone, wordpress comment form showing up on the pages.

I never used that plugin before. I see you have strange errors coming out of something and I think I can sense the malignant evil radiating from the jetpack plugin, Please disable it since in my experience the only thing that plugin is consistent in is breaking every other plugin. See if the form returned, which I have a feeling it will once those errors are squared away. http://i.imgur.com/SUXkwzq.png
